ncurses terminfo error when trying to import pwntools from a sage script

[turbobato]

Steps To Reproduce

1. MacOS Sonoma 14.7.1
2. With sagemath 10.4 installed using the 3-manifolds binary, with pwntools installed using %pip install pwntools in a sage shell
3. Create a .sage file containing import pwn
4. Run this file in a terminal, e.g in macOS Terminal
5. I get the following error : File "/Users/gjazeron/Library/SageMath-10-4/lib/python3.12/site-packages/colored_traceback/colored_traceback.py", line 34, in _get_term_color_support curses.setupterm() _curses.error: setupterm: could not find terminfo database(see below for full trace)

Expected Behavior

Expecting the import to work correctly

Actual Behavior

I get the following error :

$ sage ~/test.sage
Warning: _curses.error: setupterm: could not find terminfo database

Terminal features will not be available.  Consider setting TERM variable to your current terminal name (or xterm).

_curses.error: setupterm: could not find terminfo database

With test.sage being composed of the only line import pwn

Additional Information

I've tried setting the TERM and TERMINFO environment variables, with no success.

After discussing a bit with the maintainer of 3-manifolds MacOS sage project (discussion here) we figured out the issue comes from the following lines in the /venv/bin/sage script

 unset TERM  # See Issue #12263
 # sage-run rejects all command line options as the first argument.
  exec sage-run "$@"

Which is related to issue Issue #12263.

And so even if I set TERM env variable back, it doesn't work.

Environment

• OS: macOS Sonoma 14.7.1
• Sage Version: 10.4 from 3-manifold project

Checklist

• I have searched the existing issues for a bug report that matches the one I want to file, without success.
• I have read the documentation and troubleshoot guide

Please, try this:

import os
os.environ['TERM'] = 'linux'

import pwn

It works for me.

This works ! However, why is the TERM environment variable unset by sage ?
